[GLLUG] postfix relayhost

[Michael George]

I have reached my tipping point...  I have been letting my home system 
do final delivery of all my mail sent from my home account.  However, 
there are some places that will not accept mail from an IP address in a 
dynamic range of IPs.

I run postfix and I can set the relayhost to send all mail through my 
IPSs mail system, but it still doesn't seem to work.  I get:

Could not deliver message to the following recipient(s):

Failed Recipient: linux-user at egr.msu.edu
Reason: Remote host said: 554 5.7.1 Service unavailable; Sender address
+[george at mutualdata.com] blocked using dsn.rfc-ignorant.org; Not 
supporting null
+originator (DSN)

I can successfully send mail to my idealso.com account through the relay 
host, but the mail to egr.msu.edu fails whether I use the relayhost or 
not.  What do I need to change in my config so that the mail can be sent?
